SPECIFICATION forming part of Letters Patent No. 650,270, dated May 22,1900.

Application filed January 25, 1900. Serial No. 2,767. (No model.)

T0 @ZZ whom, it may concern:

Be it known that I, JOSEPH PERRIN, a citizen of the United States,residing at Lordsbnrg, in the county of Bottineau and State of NorthDakota, have invented certain new and useful Improvements inOultivators; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of this specification.

The invention relates generally to cultivators for potatoes or for anyplants which are grown in rows, and has for its special object to savetime and expense in raising a crop.

Figure l of the drawings is a perspective view of my double cultivator.Fig. 2 is a plan View of my cultivator blade or tooth shown in the formof a blank, the shape of flanges, their position, and that of the pointbeing illustrated by the aid of dotted lines; and Fig. 3 is a bottomview of the tooth, shoe, and standard, showing how one flange turnsunder the shoe, while Fig. l shows how the other flange passes down thesides of the standard and shoe.

In the drawings, A A represent two parallel plow-beams connected by thetwo bars or spacers B B, which are at right angles thereto. The spacersB have near pue end a series of holes b, lwhich may be made to registerwith vertical holes a in one of the plow-beams, so as to receive a pinor fastening C. This enables the plow-beams to be set at a greater orless distance apart to correspond with that between the rows of plants.b represents a series of holes in the front spacer, through which goes apin which passes through opposite eyes of a yoke b2, carrying the ringb3. The draft may thus be adjusted.

D represents the plow-standards, forwardly inclined and supported at thebottom by the front of the shoe E, which also supports at the rearforwardly-inclined handles F, which may or may not be provided with aspacer-rod G.

H represents my peculiar plow-point, which is provided with the slit 71which marks the dividing-line between the point 7L and the shank h2. Thelatter has a liange h3, which goes under the shoe, while on the forwardincline is a flange 7a4, which passes down the side of both standard andshoe, the said shank 'being then screwed or bolted to the moldboard I,as well as to the standard and shoe. The moldboard I does not performthe function of .a moldboard which turns a furrow, but merely pressesthe loose dirt to the middle of row, which a double-moldboard plowsubsequently turns back to the plants. The plow-point H acts like theshare of a subsoilplow merely to cut under and crumble the soil, whichis then pressed by both cultivators together in the middle of the row toform an elevation, which is afterward split by the double-moldboardplow.

What I claim as new isv In cultivators, the plow-point H having pointh', shank h2 and flanges 7137# combined as shown with standard D, shoeEand moldboard I, the flange 713 being bent around the front end of theInoldboard and shoe while the ange h4 is bent around the side ofstandard and shoe, for the purpose set forth.

In testimony whereof I aiiix my signature in presence of two witnesses.

JOSEPH PERRIN. Vitnesses:
